I mean Niteowl is right there. There's someone who also does his best to fight for what is right, without being a volatile homophobe and racist, who doesn't die needlessly when he realizes sometimes there isn't much one man can do against someone as powerful as Veidt.

It's telling people don't go for him, the person we actually are in a situation like this, and instead devolve into Rorschach's screaming lunacy. This is what Moore is confused about- not that people aren't siding with Veidt, but that people are so willing to dehumanize into a creature of violence and anti-thought instead of recognizing themselves in the shlubby guy who was just too late.
